Three dimensional jigsaw puzzle

ABSTRACT

A three dimensional jigsaw puzzle includes a topmost puzzle piece, a bottommost puzzle piece and mediate puzzle pieces of different dimensions. A connection device is provided between two adjacent puzzle pieces to facilitate combination of the two adjacent puzzle pieces such that an object is formed after the combination of all the puzzle pieces.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a three dimensional jigsaw puzzle, andmore particularly to a three dimensional jigsaw puzzle composed ofmultiple plates interconnected to one another so as to form a threedimensional object.

2. Description of the Prior Art

A conventional plan jigsaw puzzle is composed of multiple pieces eachwith multiple protrusions and cutouts. With the mutual correspondencebetween the protrusions and the cutouts, two adjacent pieces areconnected together. Therefore, little by little, a complete picture isformed. The difficulty of the jigsaw puzzle depends on the number of thepieces involved. This kind of jigsaw puzzle does provide entertainmentto the player. In order to increase the fun of playing with jigsawpuzzles, a three dimensional jigsaw puzzle is introduced to the marketto challenge the player's patience and skill.

The 3D jigsaw puzzle is composed of multiple pieces and may somehowinclude a bladder. When the 3D jigsaw puzzle includes the bladder, theplayer is able to depend on the spherical contour of the bladder andplace each of the pieces on the outer periphery of the bladder to manageto connect every two adjacent pieces. When there is no bladder providedto the 3D jigsaw puzzle, the player will have to depend on his/her ownskill to gradually form a three dimensional pattern.

No matter what kind of jigsaw puzzle previously described, the piecesare interconnected to one another in a plan surface or a curved surface.That is, the space usage is confined and fixed and the challenge to theplayer's patience and skill is small.

To overcome the shortcomings, the present invention tends to provide animproved laminated 3D jigsaw puzzle to mitigate the aforementionedproblems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide an improvedthree dimensional jigsaw puzzle having multiple pieces of differentdimensions such that after the pieces are interconnected one another, athree dimensional object is formed.

Another objective of the present invention is that a connection deviceis provided to the three dimensional jigsaw puzzle to help position twoadjacent pieces.

Still another objective of the present invention is that a boxconfigured to have multiple receiving recesses defined to receivetherein the pieces so that when the 3D jigsaw puzzle is not in use, the3D jigsaw puzzle is compact for storage.

Other objects, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1-3, it is noted that the 3D jigsaw puzzle inaccordance with the present invention includes multiple puzzle pieces.In this embodiment, reference numerals (1˜20) are respectively assignedto a corresponding one of the puzzle pieces and the multiple puzzlepieces are divided into a topmost puzzle piece (1), a bottommost puzzlepiece (20) and mediate puzzle pieces (2-19). A connection device isprovided between two adjacent puzzle pieces to facilitate assembly ofthe two adjacent puzzle pieces. In this embodiment, a puzzle piece (2)is provided with connection rods (22) extending from a bottom thereofand connection holes (21) defined in a top face thereof. A puzzle piece(3) is provided with connection rods (32) extending from a bottomthereof and connection holes (31) defined in a top face thereof. Withthe extension of the connection rods (22) into the connection holes(31), the puzzle pieces (2,3) are combined. In addition, the connectionrods extending from a bottom of the puzzle piece (1) are able to extendinto the connection holes (21) of the puzzle piece (2) so as to combinethe puzzle pieces (1,2). Alternate embodiment of the connection device,as shown in FIG. 4, is that the puzzle piece (2) is provided withmagnetically positive material receive therein and the puzzle piece (3)is provided with magnetically negative material received therein suchthat the attraction between the magnetically positive material and themagnetically negative material facilitates the combination between twoadjacent puzzle pieces (2,3).

With reference to FIG. 5, to facilitate storage and tidiness, a box (30)is provided and has multiple receiving recesses (301) defined therein toreceive the puzzle pieces (1˜20) of different dimensions. That is, eachof the receiving recesses (301) is of different dimensions so as toaccommodate the puzzle pieces (1˜20).

With reference to FIG. 6, it is noted that each puzzle piece (1˜20) maybe divided into two halves so that when the puzzle pieces (1˜20) arereceived in the box (30) (as shown in FIG. 5), every available spaceinside the box (30) is able to be used.

With reference to FIG. 7, a puzzle piece (15), for example, is providedwith multiple recesses (155,157) such that two puzzle pieces (5,7) areable to be received in the puzzle piece (15). The purpose of theprovision of the recesses in one puzzle piece is to save space in thebox (30) and to organize the puzzle pieces (1˜20).

With reference to FIG. 8, it is noted that an image may be printed ontop of the box (30) so that a customer or a player of the jigsaw puzzleis able to identify the content inside the box (30) without the troubleof opening the box (30) to find out what exactly is received in the box(30).

It is to be understood, however, that even though numerouscharacteristics and advantages of the present invention have been setforth in the foregoing description, together with details of thestructure and function of the invention, the disclosure is illustrativeonly, and changes may be made in detail, especially in matters of shape,size, and arrangement of parts within the principles of the invention tothe full extent indicated by the broad general meaning of the terms inwhich the appended claims are expressed.
